UNHED ATES JOHl A. DIETERICH, OF CLEVELAND, OHIO, ASSIGNOR ONE-HALF TO GEORGE BLUMENSTOCK, OE? CLEVELAND. OHIO,

SPRING-WHEEL.

To all whom 'it may concern:

lie, it known that l, JOHN Dm'rnlucil, a citizen of the United States, residing at Cleveland` in the county ot Cuyahoga and Slate otz Uhio, have invented a certain new aud useful Improvement in Stui'iiig-lflieels, ot which the following is a full, clear, and exact description7 ,reference being had to the accompanying drawings.

This invention relates to a spring wheel for nee upon vehicles7 aud aims` to produce a spring wheel which shall be Simple in construction, durable and strong. and resiliently bear the weight of the vehicle and ity con- Ltentghtransportiug the same over the road ulith iniuimum of jarring etlect. i

Generally .lipealiinex the invention comprises the elements and eombinatione thereof set `t'orth in the accompanying claims.

Reference should he had to the accompanying drawings7 in which- Figure 1 is an elevation of a spring wheel embodying the features of n y invention, certain parte of the wheel being' removed to more ett'ectually disclose the, internal structure; Fig. 2 is a vertical section through a spoke, hub and the tread; Fig. 3 is a section through the hub and tread between the spokes; lig. et is a section through the tread illustratingl the use ot a rubber tire in con-` nection with the wheel; and Fig. 5 is a fragmentary plan view of the tire Shown in Fig. 2".

The hub and spoke portions ot' the wheel are .formed ot'l two symmetri yal halves in the longitudinal direction of the wheel. These halt' portions may be formed of a single sheet of Sheet metal either by single stamping or by a forging, or in any other manner7 and it. is also evident that the spokes and hub might be formed other than from a` single sheet of metal.

The two symmetricay portions of the wheel are joined together la' means 01' bolts and nuts 12 which engage the two halves of the wheel and ,hold the saine together.

The spokes are tubular, .ind at their outer ends are' all joined to two parallel annular flanges l() and 11 which entirely encircle the wheel. The hub may also be made hollow which conduces to the reduction of the weight of the wheel.

The `tread of thewheel ie entirely independent of the spokes and is `formed with-` a tire receiving portion 13 and two parallel Specification of Letters Patent.

depending flanges; 14 and 15 which are spaced apart a sutiieient distance so that their outer surfacee may eng-awe the inner surfaces upon the flanges 10 and 11. To the portion. 13 otl the tread are secured a Series et posts 1G. which eorrespoml in number to the spokes and are spared apart a sutlicient distance so that each post may be arranged opposite to a spoke and in alinement therewith. "iheee poets 16 may be secured to the part 13 ot the tread by Screw threading the .Qaid poete. or they may be't'astened in any suitable manner.

A t the inner lower end of the Spokes is secured a post 17 which is secured to either halt portion of the hub 1S.

SpringsI l?) occupy the space within the hollow spokes and at their outerendgencir: cle the poets 1C and at their inner ends eneirele. the posts 1T.I The springe are selected et a proper stillness to be Suitable for the class of vehicle upon which' they are to be. used. The springe when in aibled position in the wheel are under compression, which prevents any rattling of the. parts.

rihe tread 13 otl the wheel may be formed saucer sha-pe, as will be evident from inspection of Fig. 2 for the purpose ot engaging and holdinga tire indicated at 20. This tire may be a plain steel band, as shown in Fig. 2, or it. may be a Steel band formed with proj eetions upon the outer side thereot2 as indicated in Fig. 3, and shown with more detail in Fig. 5. Or, it desired, a 'rubber tire, as Shown at 21, may be used.

The wheel will be complete and operative as above described, but in order to more elt'ectually prevent dust from working its` way into the interior of the Spokes secure annular dust strips 22 and 23 upon opposite sides et the tread, the said strips extending toward the hub o the wheel a sutiieient distance to cover the upper edges of the tianges 10 and 11. These protecting members 22 and 23 are Secured to the tread of thewheel by screw threaded bolts so 'that they are readily removable.

In assembling the wheel, one halt of the hub-and spoke portion is assembled in proper relation to the tread, the Springe 19 are then ineertcd in place and the other half of the hub and spokes is assembled in its proper relation to the wheel and the halves of the hub and spokes are secured together by the bolts. The dust guards 22 and 23 are then placed in position and the desired form of will not compress the springs to such an exl' tent that the flanges 10 and 1l will engage the tread 13. In this way any bumping is obviated. It is understood that the wheel herein 'shown and described is intended for use upon all classes of vehicles whether thesaid I vehicles be for light road use .por heavy assembled, the outer end .of the spokes being trucking. 2O

Having thus described my invention, what I claim is: u y

1. A spring Wheel comprising a hub and a plurality 5f spokes, the hub and spokes being formed in symmetrical halves, the said spokes being hollow, when the halves are joined by parallel anges, a tread portion coperating with the flanges, said tread be` ing capable of moving independently of the hub'and spokes', springs within the spokes and extending throughout the length thereof, the outer ends of said springs being' secured to the treadportion, the outer portions of the spokes being rounded, the said springs being deflected over said rounded portion when the wheel is in operation.

2. A spring wheel comprising a hub and a plurality of hollow spokes, the said hub and spokes being formed in two symmetrical halves and of a single piece of metal, the oufter ends of the spokes being joined by parallel flanges, a tread portion cooperating with 'the flanges, said tread portion being capable of rotary movement independent oi' the hub and spokes, springs within the spokes and secured at their outer ends to the tread portion.

8. A spring wheel comprising a hub and y a plurality oi hollow spokes, the said spokes being joined at their outer ends by continu` ouswebs forming flanges, the said hub and spokes being formed in twol symmetrical halves formed from a single sheet of metal, a tread portion formed with depending ianges which cooperate with the 'flanges before mentioned, said tread portion being capable offrotary movement independent of the hub and spokes, springs within the hollow spokes and secured at their outer ends to the tread portion.

In testimony whereof, I hereunto allix my l'signature in the presence of two witnesses. JOHN A. DTETERlCI-I. Witnesses: Y. BRENNAN B, WEsi.
